摘　　要：为了进一步提高传统最优空域滤波算法的性能,本文提出了一种基于极化敏感天线阵列的极化域-空域联合的自适应波束形成算法.在给出了算法的信号模型和算法原理的基础上,详细的阐述了该算法实现极化域-空域联合自适应滤波的机理,然后利用计算机仿真较全面地分析和比较了算法的性能.理论分析和仿真结果表明,本文提出的新算法在提高输出信干噪比和削弱指向误差影响等方面明显地优于传统的最优滤波方法.In order to improve the performance of the traditional optimum space filtering algorithm, a polarizationspace adaptive beamforming algorithm based on PSA（Polarization Sensitive Array） was presented in this paper. The signal model and ba sic idea of the proposed algorithm were given,and then the principle of polarizationspace adaptive filtering was discussed.Further more, the performance of the proposed algorithm was analyzed and compared through numerical simulations. Theoretical analysis and simulation results show that the proposed algorithm can effectively improve the SINR and reduce the effect of pointingerror, and that it obviously outperforms traditional optimum filtering approach.
